IIVIPROVED MACHINE FOR FINISHING SOLDERED- TUBING.

Specification forming part of Letters Patent No. 20,5129, dated June 8,1858.

To all whom. it may concern.-

Beit known that I, EDMUND J ORDAN, of Waterbury, in the county of NewHaven and State of Connecticut, have invented a new and Y useful Machinefor Finishing Soldered Tubing;

tached plan view of the clamp. Fig. 4 is a transverse section of thesaine, taken in the line y y, Fig. 3.

Similar letters of reference indicate corresponding partsin the severalfigures.

This invention consists in a peculiar means employed for operating afile or cutter for the purpose of filing or finishing off the solderedseams of tubing.

The invention also consists in a peculiar clamp for holding the tubingwhile being operated upon by the file or cutter.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents a rectangular frame, which may be constructed in any propermanner to support the working parts.

B is a driving-shaft placed transversely in one end of the machine, saidshaft having a crank, C, at one end of it.

To the crank C a connecting-rod, D, is attached,the outer end of saidrod being pivoted to a bar, E,which is pivoted to a sliding plate, F,said plate being iitted between guides G G, attached to one side oftheframe A.

To the lower part of the bar E lateral arms a a are attached-one at eachside-and to these arms clamps b are fitted, said clamps retaining each ale or cutter, c, the cutters being formed of steel plates, cut on theirunder or face sides in any proper manner to form cutting-edges, similarto a rasp or file. The connecting-rod D is attached to the barE abovethe pivot d, which attaches it to the sliding plate F.

On the sliding plate F, or on a projection thereon, two lugs, dd,areformed, and through these lugs or ears screws e epass, between the innerends of which the upper end of the bar E is fitted and works, saidscrews serving as stops.

To the upper part of the frame Atwo plates or stops, G G', are attached,the use of which will be presently shown.

H H are two levers, which are pivoted in the frame A, as shown at f.

In the outer ends of the levers H concave journals g of a bar, l1, arefitted, the journals being fitted loosely in their bearings.

To each end of the bar h a cross-plate, i', is attached, saidcrosslplates being connected with the j ournals,and to the lower partsofthe -plates i the lower ends of two plates, I I, are

attached-*one at each side of the bar h-the plates I extending upward alittle higher than the bar h.

Transverse] y through the plates I I a screwrod, j, passesand a lever,lc, is attached to the outer end of said rod, the inner end of saidlever forming a cam which bears against abar,

Z, tted in a slot in the screw-rod j. The levers H H are connected bymeans of supplementary levers m m to a rod, J, which is attached to atreadle, K.

The operation is as follows: The attendant or operator grasps a tube, L,and places it seam uppermost between the upper ends ofthe plates I I,which, when not otherwise acted upon, are kept distended by springs it.The upper ends of the plates I I are made to grasp the tube L and holdit iirmly by adjusting the lever 7c. Motion is then given thedriving-shaft B in any proper way, and the les or cutters c are movedback, and farther over the seam of tube L, the latter being pressedupward against the files or cutters by depressing the outer end of thetreadle K. The cutters c act alternately on the tube as the bar E istilted at the end ofA each movement. The action ofthe rod D serves tokeep the bar E and cutters in proper position, and the tilting of thebar E, and consequently the cutters, is assisted in being tilted alittle in advance of the action of rod D, by means of the stops G G, inconsequence ofthe upper end of the bar E striking against saidprojections. By this means the device vis made to operate smoothly, thestock, which is fitted to a reciprocating slide, momentum ofthe files orcutters and the cutter- F, and operated by means of the connectingstockbeing neutralized at the end ofeach stroke rod D, crank C, and stops GG', substantially by the advance tilting movement described. as and forthe purpose set forth.

By this inventionthe tubes may be nished- 2. The clamp formed of the twoplates I I, that is, have their soldered seams smoothly l attached tothe leversHH,Which are connectfiled or rasped in a perfect manner andwith ed to atreadle, K, the Whole being arranged to great facility.operate as and for the purpose specified.

Having thus described my invention, what EDMUN D J ORDANv I claim asne'W, and desire to secure by Letters Witnesses:
